Update all docker images already pulled.

When we want to update all images that pulled. This is a command to use update all images at once. (This command will pull the latest tag)

docker images | grep -v REPOSITORY | awk '{print $1}' | xargs -L1 docker pull

I found this command a long time ago and I cannot remember the reference. I am sorry for the owner.

Today I found a problem on MacOS with this command and fixed to use

docker images | grep -v REPOSITORY | awk 'BEGIN{OFS=":"} {print $1,$2}' | xargs -L1 docker pull

@goffity the following:

docker images | grep -v REPOSITORY | awk 'BEGIN{OFS=":"} {print $1,$2}'

can be easily done with:

docker images --format "{{.Repository}}:{{.Tag}}"

So the final command would be:

docker images --format "{{.Repository}}:{{.Tag}}" | xargs -L1 docker pull

That command will update all images, but will pull maybe more than you need. For instance, I use python:3.6-alpine (40MB) and postgres:13-alpine (158MB). That command downloads a new python:latest (880MB) and a new postgres:latest (314MB).

The command to update your existing images is:

docker images | grep -v ^REPO | sed 's/ \+/:/g' | cut -d: -f1,2 | xargs -L1 docker pull

(my postgres:13-alpine was updated now, to 160MB)

And to clean unused and untaged images after that, run:

docker image prune
